Abstract：In order to protect audio multimedia intellectual property rights. A audio zero-watermarking algorithm based on 3-level discrete wavelet transform is proposed in this paper. In the scheme, an original audio is divided into frames. Each frame is decomposed on discrete wavelet transform and singular value decomposition. Watermarking key is constructed by the original audio decomposed. The simulation results demonstrate that the algorithm has strong robustness against the common audio signal processing such as low-pass filter,Gaussian noise,up-sampling,down-sampling, re-quantization, echo, MP3 compression, reverse amplitude. It is efficient to resolve the trade-off between the transparence and robustness of the watermarking system.?????
